One building by this arch
One building by this architect was designed as a hotel and office block wrapped around an opera theater and had a 17-story tower. Another of his buildings is similar to an earlier edifice, except that its façade has ornamental terra cotta instead of bare brick rectangular columns. This architect and his partner designed the Auditorium Building in Chicago and Buffalo's (*) Guaranty Building. He also made a building with a two-story sandstone base below a brick façade topped with an overhanging terra cotta cornice. That building has a frame made entirely of steel. For 10 points, name this collaborator of Dankmar Adler who designed early skyscrapers like St. Louis's Wainwright Building.
